Default Partial Mash question

I'm doing my first partial mash today and I have a quick question. I've heard that it is recommended that your mash be made up of around 50% 2-row pale malt to promote good enzyme activity, but since I'm using Light DME instead of pale malt in my recipe (and have no pale malt in my mash) am I going to run into mashing problems?

Cheers!

What grains do you have for the mash?

The mash consists of crystal 20L, aromatic, dextrine, peat smoked, and chocolate malts.

That looks like more of a specialty grain bill for a steeping recipe - in order to be a partial mash you'd need to add some base grain (the 2-row pale malt). Without that you're not mashing anything, you're just steeping the specialty grains.

If you want to do a partial mash, you'll need to add a couple of pounds of 2 row pale malt and remove 1-1.25 lbs of the DME. Aromatic malt has some enzymes but generally you need the high enzymatic power of the 2-row to help convert malts that don't have their own (the dextrine for instance)

Thanks, you just saved my beer. I'm running to the homebrew shop now for some 2-row.

Cheers!

Is single temperature infusion an ok method for the grains I have?

(The mash consists of 2-row pale, crystal 20L, aromatic, dextrine, peat smoked, and chocolate malts.)

A single infusion will work.
